I am working with Jackson XML (apache came) to unmarshal XML file to object.
First, I read the file XML by the split, it is OK in debugging (body is String with all data)
<split>
<tokenize token="root" xml="true" group="1000"/>
<!--
body is a String with all XML content, exp:
<rooter>
<node>
<name1>value1</name1>
<name2>value2</name2>
</node>
<node>
<name1>value3</name1>
<name2>value4</name2>
</node>
<node>
<name1>value4</name1>
<name2>value6</name2>
</node>
</rooter>
-->
<unmarshal>
<custom ref="jack" />
</unmarshal>
<!--
body now is a map with only 1 value.
<node>
<name1>value4</name1>
<name2>value6</name2>
</node>
-->
</split>
However when I ummarshal it, it's body still only one value
<dataFormats>
<jacksonxml id="jack"/>
</dataFormats>
How can I get the result as a map with all the values?

I'm trying to get tag "" from xml below.
If i execute request like this:
WITH x(col) AS (select'<document xmlns="http://example.com/digital/back/" xmlns:ns2="http://example.com/digital/back/complexId" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="">
<header>
<docId>13a2f29a28b12ecb</docId>
<dt>2018-12-10T11:59:48.112+03:00</dt>
</header>
<pay>
<reqTransfer id="154638">
<source>
<card>
<virtualCardNum>4B74C1EE187</virtualCardNum>
<bsc>VISA</bsc>
</card>
</source>
</reqTransfer>
</pay>
</document>
'::xml)
SELECT xpath('/document/pay/reqTransfer/source/card/bsc/text()', col) AS bsc
FROM x;
I get {}, but if I relpace the document start tag
<document xmlns="http://example.com/digital/back/" xmlns:ns2="http://example.com/digital/back/complexId" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="">
with <document> or even <document xmlns="">, I get { VISA } - that is right.
What should I do to replace <document xmlns="..."> with <document> or get { VISA } without replacement?
If you are working with XML namespaces, they are worth mentioning in your Xpath queries too, i.e. use
SELECT xpath('/d:document/d:pay/d:reqTransfer/d:source/d:card/d:bsc/text()', col,
ARRAY[ARRAY['d', 'http://example.com/digital/back/']]) AS bsc

I want to get the value of the payloadID on the DocumentReference element. This is what I have tried so far:
BEGIN
Declare #Xml xml
Set #Xml = ('..The XML From Above..' as xml)
END
--no value comes back
Select c.value('(/*/DocumentReference/#payloadID)[0]','nvarchar(max)') from #Xml.nodes('//cXML') x(c)
--no value comes back
Select c.value('#payloadID','nvarchar(max)') from #Xml.nodes('/cXML/*/DocumentReference') x(c)
--check if element exists and it does
Select #Xml.exist('//DocumentReference');
I tried this in an xPath editor: //DocumentReference/#payloadID
This does work, but I am not sure what the equivalent syntax is in SQL
Calling .nodes() (like suggested in comment) is an unecessary overhead...
Better try it like this:
SELECT #XML.value('(//DocumentReference/#payloadID)[1]','nvarchar(max)')
And be aware, that XPath starts counting at 1. Your example with [0] cannot work...
--no value comes back
Select c.value('(/*/DocumentReference/#payloadID)[0]','nvarchar(max)') from...
I'm getting struggle in looping the entries in data weaver. Below is the Input and the expected response.
Not sure how to make loop(I need to get RecordEntry and each entry with 'IndividualEntry') .
Input xml : Record entry tag in input xml is 3, but I might get many. So need to make a loop as dynamic.
<?xml version="1.0" encoding="UTF-8"?>
<Records>
<storenumber />
<calculated>false</calculated>
<subTotal>12</subTotal>
<RecordsEntries>
<RecordEntry>
<deliverycharge>30.0</deliverycharge>
<entryNumber>8</entryNumber>
<Value>true</Value>
</RecordEntry>
<RecordEntry>
<deliverycharge>20.0</deliverycharge>
<entryNumber>7</entryNumber>
<Value>false</Value>
</RecordEntry>
<RecordEntry>
<deliverycharge>1.0</deliverycharge>
<entryNumber>6</entryNumber>
<Value>false</Value>
</RecordEntry>
</RecordsEntries>
</Records>
Expected Response ( I'm expecting the below response)
<?xml version="1.0" encoding="UTF-8"?>
<orders>
<order>
<StoreID />
<Total>false</Total>
<IndividualEntry>
<Number>8</Number>
<DeliverCharge>30.0</DeliverCharge>
</IndividualEntry>
<IndividualEntry>
<Number>7</Number>
<DeliverCharge>20.0</DeliverCharge>
</IndividualEntry>
<IndividualEntry>
<Number>6</Number>
<DeliverCharge>1.0</DeliverCharge>
</IndividualEntry>
</order>
</orders>
My Data weaver Transformation as below
%dw 1.0
%output application/xml
---
{
orders: {
order: {
StoreID:payload.Records.storenumber,
Total: payload.Records.calculated,
IndividualEntry: payload.Records.RecordsEntries.*RecordEntry map {
Number:$.entryNumber,
DeliverCharge:$.deliverycharge
}
}
}
}
Currently I'm getting response as below ( I don't know how to make each Record entry as a IndividualEntry tag, and also here element tag is added in extra which is not required in my case)
<?xml version="1.0" encoding="UTF-8"?>
<orders>
<order>
<StoreID />
<Total>false</Total>
<IndividualEntry>
<element>
<Number>8</Number>
<DeliverCharge>30.0</DeliverCharge>
</element>
<element>
<Number>7</Number>
<DeliverCharge>20.0</DeliverCharge>
</element>
<element>
<Number>6</Number>
<DeliverCharge>1.0</DeliverCharge>
</element>
</IndividualEntry>
</order>
</orders>
Could any one help me in fix this. Thanks in advance.
One way to do it:
orders: {
order: {
StoreID: payload.Records.storenumber,
Total: payload.Records.calculated,
(payload.Records.RecordsEntries.*RecordEntry map {
IndividualEntry: {
Number:$.entryNumber,
DeliverCharge:$.deliverycharge
}
})
}
}
Inside an object when you put an expression between parenthesis that returns an array of key-value pairs it is evaluated and used to fill the object.

I would like to insert a new element in the following XML for each instance of a data node
Here is the initial XML that I have:
<dataCollection totalCount="12" pageCount="1">
<data>
<date>2011-11-10T00:00:00.000-05:00</date>
<dataType>PRCP</dataType>
<station>GHCND:USW00014739</station>
<value>267</value>
<address>
<home>X</home>
</address>
</data>
<data>
<date>2011-11-10T00:00:00.000-05:00</date>
<dataType>PRCP</dataType>
<station>GHCND:USW00014739</station>
<value>267</value>
<address>
<home>X</home>
</address>
</data>
</dataCollection>
And this is the XML I am trying to achieve
<dataCollection totalCount="12" pageCount="1">
<data>
<date>2011-11-10T00:00:00.000-05:00</date>
<dataType>TMIN</dataType>
<station>GHCND:USW00014739</station>
<value>267</value>
<newValue>60</newValue>
<address>
<home>X</home>
</address>
</data>
<data>
<date>2011-11-10T00:00:00.000-05:00</date>
<dataType>TMAX</dataType>
<station>GHCND:USW00014739</station>
<value>270</value>
<newValue>62</newValue>
<address>
<home>X</home>
</address>
</data>
</dataCollection>
The XML data is used as a data source for a DataGrid using the following Linq.
Dim elements = (From daDsc In xdoc.Descendants("data") _
Select Data_Type = daDsc.Element("dataType").Value, _
Raw_Value = daDsc.Element("value").Value,
newValue = daDsc.Element("newValue"))
Writing this in VB.net, but answers in C# is OK. Thanks.
Try this:
foreach (var xe in xml.Descendants("data"))
{
xe.Element("value")
.AddAfterSelf(new XElement("newValue", 42));
}
If you wish to add newValue into your XML before processing, you could do something like this:
For Each element As XElement In xml.Elements
element.SetElementValue("newValue", "something")
Next
where xml is an XDocument, loaded from your web service.
I am trying to using lxml's ElementTree etree to find a specific tag in my xml document.
The tag looks as follows:
<text:ageInformation>
<text:statedAge>12</text:statedAge>
</text:ageInformation>
I was hoping to use etree.find('text:statedAge'), but that method does not like 'text' prefix.
It mentions that I should add 'text' to the prefix map, but I am not certain how to do it. Any tips?
Edit:
I want to be able to write to the hr4e prefixed tags.
Here are the important parts of the document:
<?xml version="1.0" encoding="utf-8"?>

The namespace prefix must be declared (mapped to an URI) in the XML document. Then you can use the {URI}localname notation to find text:statedAge and other elements. Something like this:
from lxml import etree
XML = """
<root xmlns:text="http://example.com">
<text:ageInformation>
<text:statedAge>12</text:statedAge>
</text:ageInformation>
</root>"""
root = etree.fromstring(XML)
ageinfo = root.find("{http://example.com}ageInformation")
age = ageinfo.find("{http://example.com}statedAge")
print age.text
This will print "12".
Another way of doing it:
ageinfo = root.find("text:ageInformation",
namespaces={"text": "http://example.com"})
age = ageinfo.find("text:statedAge",
namespaces={"text": "http://example.com"})
print age.text
You can also use XPath:
age = root.xpath("//text:statedAge",
namespaces={"text": "http://example.com"})[0]
print age.text
I ended up having to use nested prefixes:
from lxml import etree
XML = """
<greenCCD xmlns="AlschulerAssociates::GreenCDA" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:hr4e="hr4e::patientdata" xsi:schemaLocation="AlschulerAssociates::GreenCDA green_ccd.xsd">
<personInformation>
<hr4e:ageInformation>
<hr4e:statedAge>12</hr4e:statedAge>
</hr4e:ageInformation>
</personInformation>
</greenCCD>"""
root = etree.fromstring(XML)
#root = etree.parse("hr4e_patient.xml")
ageinfo = root.find("{AlschulerAssociates::GreenCDA}personInformation/{hr4e::patientdata}ageInformation")
age = ageinfo.find("{hr4e::patientdata}statedAge")
print age.text
